I've got the following music song which can be found in these videos at YouTube:
which my friend would like to learn to play, however I don't know the full name of it (or origin).
I've tried SoundHound and Shazam apps, but they don't recognise anything. Googling didn't help either.
The 《往事》 (in Chinese) translates to: Cello "past" and some comments confirms that is the title. My friend said the title of the song could be: Almost with tears. However still I couldn't identify the origin of that song (apart of these 2 videos).
